DETERMINING AN ADJUSTMENT OF A TILT ANGLE FOR AN ANTENNA SERVING A VERTICALLY SECTORIZED CELL OF A RADIO NETWORK

摘要

There is provided a method and an apparatus for determining an adjustment of a tilt angle (α1, α2) for a beam emitted from an antenna (130) of a base station (100) which is serving a vertically sectorized cell (150) of a cellular radio telecommunication network. The method comprises (a) configuring user equipments (162, 164) being located in the vertically sectorized cell (150) with dedicated measurements, (b) collecting the dedicated measurements for a specific time interval, (c) obtaining a spatial user equipment distribution among a first sector (152) of the cell (150) and a second sector (154) of the cell (150) based on the collected dedicated measurements, (d) ascertaining an optimized spatial overlap region between the first sector (152) and the second sector (154) based on the obtained spatial user equipment distribution, and (e) determining the adjustment of the tilt angle (α1, α2) based on the ascertained optimized spatial overlap region.
